@Henry the fish keeper I'm not sure. I originally had four angelfish, but one was smaller than the rest and couldn't compete for food, and when I came back from vacation several days ago another one passed, leaving me with just these two. Yesterday one laid eggs for the first time, but they were eaten overnight and I couldn't tell if they were fertilized or not. I'll attach a picture below. The eggs are on the leaf; I'm sorry that they're hard to see.
